ABSTRACT

Objective Coronary computed tomography angiography (CCTA) is a noninvasive diagnostic modality that remains underutilized compared to functional stress testing (ST) for investigating coronary artery disease (CAD). Several patients are misdiagnosed with noncardiac chest pain (CP) that eventually die from a cardiovascular event in subsequent years. We compared CCTA to ST to investigate CP. Methods We searched MEDLINE, PubMed, Cochrane Library, and Embase from January 1, 2007 to July 1, 2018 for randomized controlled trials (RCTs) comparing CCTA to ST in patients who presented with acute or stable CP. We used Review Manager (RevMan) [Computer program] Version 5.3 (Copenhagen: The Nordic Cochrane Centre, The Cochrane Collaboration, 2014) for review and analysis. Results We included 16 RCTs enrolling 21,210 patients; there were more patients with hyperlipidemia and older patients in the ST arm compared to the CCTA arm. There was no difference in mortality: 103 in the CCTA arm vs. 110 in the ST arm (risk ratio [RR] = 0.93, 95% confidence interval [CI] = 0.71-1.21, P = .58, and I2 = 0%). A significant reduction was seen in myocardial infarctions (MIs) after CCTA compared to ST: 115 vs. 156 (RR = 0.71, CI = 0.56-0.91, P < .006, I2=0%). On subgroup analysis, the CCTA arm had fewer MIs vs. the ST with imaging subgroup (RR = 0.70, CI = 0.54-0.89, P = .004, I2 = 0%) and stable CP subgroup (RR = 0.66, CI = 0.50-0.88, P = .004, I2 = 0%). The CCTA arm showed significantly higher invasive coronary angiograms and revascularizations and significantly reduced follow-up testing and recurrent hospital visits. A trend towards increased unstable anginas was seen in the CCTA arm. Conclusions Our analysis showed a significant reduction in downstream MIs, hospital visits, and follow-up testing when CCTA is used to investigate CAD with no difference in mortality.

ABSTRACT

Background: Long-term oral anticoagulants (OAC) increases bleeding risk after the percutaneous coronary intervention (PCI) with dual antiplatelet therapy (DAPT) with Aspirin and P2Y12 inhibitors. We hypothesize that dual anti-thrombotic therapy (DATT) reduces bleeding without increased cardiovascular events. Objectives: DATT does not increase adverse cardiovascular events compared to triple anti-thrombotic therapy (TATT). Method: We searched MEDLINE, PUBMED, Google Scholar, Cochrane and EMBASE from inception to 6 April 2019 for randomized control trials (RCTs) comparing DATT to TATT after PCI. Results: We identified 641 citations (411 after excluding duplicates). Four RCTs with 5,317 patients (3,039 on DATT vs 2,278 on TATT) were included. DATT arm showed significantly reduced [total bleeding, 731 vs. 784, odds ratio [OR] = 0.51, Confidence Interval [CI] = 0.39-0.67, p < 0.00001, I2 = 71% (I2 = 0% without WOEST study)], [TIIMI major bleeding 60 vs. 80, OR = 0.56, CI = 0.4-0.79, p = 0.0009, I2 = 0%], and [TIIMI minor bleeding, 70 vs 126, OR = 0.43, CI = 0.32-0.59, p < 0.00001, I2 = 0%]. There was no difference in subsequent strokes, myocardial infarction, stent thrombosis, and mortality. A trend towards decreased non-cardiac deaths with DATT was observed, 14 vs 26, OR = 0.55, CI = 0.27-1.10, p = 0.09, I2 = 6%. Conclusions: DATT is associated with significantly reduced bleeding and a trend towards reduced non-cardiac death with no difference in adverse cardiovascular outcomes.

ABSTRACT

BACKGROUND: Recent randomized control trials (RCTs) have suggested benefit with transcatheter patent foramen ovale (PFO) closure plus antiplatelet therapy over medical treatment alone for secondary stroke prevention. MATERIAL AND METHODS: Data sources: we searched PubMed and Ovid MEDLINE from the inception until November 10, 2017 for RCTs comparing TPFO closure to medical therapy in patients with a PFO and a history of cryptogenic stroke. RESULTS: Five RCTs with 3,627 patients (TPFO closure = 1,829 versus medical therapy =1,798) were included. There was a decreased number of post-TPFO closure strokes compared to the medical therapy arm; 53 versus 80 strokes (odds ratio [OR] = 0.61, CI: 0.39-0.94, P = 0.03, I2 = 17%). Transient ischemic attacks occurred in 43 patients after TPFO closure versus 60 patients in the medical therapy group (OR = 0.80, CI: 0.53-1.19, P = 0.26, I2 = 0%). There was a higher incidence of atrial fibrillation in the TPFO closure group, which occurred in 75 patients, compared to 12 patients in the medical therapy group (OR = 5.23, CI: 2.17-12.59, P = 0.0002, I2 = 43%). There was a trend toward a decreased number of neuropsychiatric events in the TPFO closure closure group compared to the medical therapy group; 42 versus 67 neuropsychiatric events (OR = 0.71, CI: 0.48-1.06, P = 0.09, I2 = 0%). CONCLUSIONS: TPFO closure plus antiplatelet therapy is superior to medical therapy in patients with a PFO and cryptogenic stroke. PFO closure is associated with new-onset atrial fibrillation and a trend toward reduced neuropsychiatric events.

ABSTRACT

Acute kidney injury (AKI) is commonly associated with aortic valve replacement. Surgical aortic valve replacement (SAVR) is a known risk factor for AKI but little is known about the short- and long-term effects of transcatheter aortic valve implantation (TAVI). The purpose of our analysis is to identify the short- and long-term effect of TAVI on renal outcomes. We searched Medline and PUBMED from January 1, 2000 to November 6, 2017 for randomized control trials (RCTs) comparing TAVI to SAVR in patients with severe aortic stenosis. Three hundred sixty-nine trials were identified, 6 RCTs were included in our analysis. RevMan version 5.3 was used for statistical analysis. Heterogeneity is calculated using I2 statistics. Primary outcomes were AKI within 30 days and 1 year of TAVI, and requirement for renal replacement therapy. We included 5,536 patients (2,796 in TAVI and 2,740 in SAVR arm) from 6 RCTs. Baseline characteristics were similar. There was reduced incidence of AKI at 30 days of TAVI compared with SAVR, 57 versus 133 (odds ratio [OR] 0.40, confidence interval [CI] 0.28 to 0.56, p <0.00001, I2 = 7%) with no difference at 1 year (OR 0.65, CI 0.32 to 1.32, p = 0.23, I2 = 76%) and need for renal replacement therapy OR 0.95, CI 0.50 to 1.80, p = 0.87, I2 = 0%). Permanent pacemaker was more frequent in the TAVI arm compared with SAVR arm, 379 versus 110, (OR 3.75, CI 1.67 to 8.42, p = 0.001, I2 = 89%). In conclusion, TAVI is associated with a reduction in AKIs at 30 days despite the exposure to contrast and higher incidence of new permanent pacemaker placement.
